Abstract
Abstract Understanding the response of winter field peas ( Pisum sativum spp. arvense L.) to vernalization is essential for cultural and breeding programs designed to improve seed yield and quality. The objective of this study was to determine the influence of vernalization on flower position, earliness of flowering, yield, and protein content of ‘Fenn’ winter field pea. Seedlings, 2‐days‐old, were vernalized at 2 to 4 C for 0 to 4 and 0 to 5 weeks in two consecutive experiments. Vernalization significantly accelerated flowering by reducing the number of nodes and days after treatment to the first flower. Progressive acceleration of flowering was observed as duration of exposure to cold treatment increased. Maximum acceleration of flowering was attained by exposure to 4 weeks of cold temperature. Vernalization slightly inhibited vegetative dry matter production and seed yield. Percent protein in the seed was slightly increased by vernalization because equal amounts of N were translocated to smaller sinks induced by the cold treatment. Total seed protein/plant was not affected by the cold treatment.
